Yes! That's Benito Mussolini in my avatar! Why? I wanted an avatar that could wear hats, did a Google Image search on my name, and came across this; note the name of the artist. How could I not!? Plus, some might actually find it more fitting! (I'll change it back to the ol' standard after Winter Bash.)

Random praise for me:

You might see some necro-like-bumps from me. I'm trying to slowly edit/delete all my HINT answers from the site. I am also trying to stay away from giving hint answers in the future.

The last 10 answers I've posted:

  1. Zero sets in Mrówka spaces (22-Nov-2014)
  2. Regarding functions on $\omega_1$ (10-Nov-2014)
  3. Possible behaviours of the cofinality-of-neighbourhood function for topological spaces $X$ that are connected. (6-Nov-2014)
  4. Example of a $T_1$ space that does not have the property that every compact subspace of $X$ is closed. (5-Nov-2014)
  5. Why wouldn't someone accept Gentzen's consistency proof? (15-Oct-2014)
  6. Consistency of restricted forms of Martin's Axiom with the negation of the Continuum Hypothesis (8-Oct-2014)
  7. Spaces where all compact subsets are closed (2-Oct-2014)
  8. Is there always an equivalent metric which is not complete? (24-Sep-2014)
  9. Mary Ellen Rudin's proof that all metric space are paracompact (3-Sep-2014)
  10. Operators on the family of all subsets of a topological space that maybe generates a base for these family. (28-Aug-2014)

Yes, my answer-posting rate has slowed to a crawl. But I am generally happier with the questions I've been answering (and the answers I'm giving).

And the question your meta-question was about was also removed by you (2 days ago, as you say).

Close-flags put questions into the close votes review queue, and not into the moderator flag queue. (Though there is nothing preventing moderators from being active in these queues, our efforts are often spent elsewhere.)

Mainly, there have been a lot of nominations in less than 24 hours in, and many of these are users with little involvement in the site, especially the meta side. IIRC, in the previous election it took a couple days to achieve even four.

It is possible that "close-flags" are omitted from the number of flags counted above.

I don't disagree with you that the rep requirements for being a moderator here should be increased. 10K is probably too much; even SO only requires 3K. But here is probably not the place to bring this up. That is something for meta. Seeing how things are developing so far, I am planning to bring this up myself, but likely not before the new year. Though if someone else does, that's fine, too.

Funny how the text appears to match up so well. I mean, that you are both currently "guiding 5 students for Ph.D. degree under VTU" is quite the coincidence.

Really? I thought that Dr. V. Ramachandramurthy was the head of the mathematics department of MSRIT.
